Samsung’s new Galaxy Alpha Smartphones comes with a nice looking aluminium frame but lacks in places like a slot for storage cards. The last months showed a steady decrease in price for the Samsung Galaxy Alpha which makes the phone an pretty interesting piece of technology on the phone market. In this tutorial we will show you how to root your Samsung Galaxy Alpha G850F. 


In this tutorial we use the CF-Auto-Root method which triggers the internal KNOX counter of the phone. This voids your waranty and can be detected by Samsung. CF-Auto-Root also doesnt install a custom recovery like the ClockworkMod. Apps like TitaniumBackup and others that need root access work flawlessly.

Samsung Galaxy Alpha Root Tutorial

  1. Download the CF-Auto-Root Package for your device

  6. Connect your Samsung Galaxy Alpha to your PC (use the standard USB-Cable that came with the phone) and launch Odin
  7. If Odin is able to detect your phone, one of the ID:COM boxes should turn yellow (this needs to happen in order for the rest of the steps to work)
  8. Klick on „PDA/AP“ and select the previously downloaded CF-Auto-Root Image. Keep in mind that the CF-Auto-Root Files are compressed as .zip files. Those need to be extracted, the file we select unter „PDA/AP“ should have „.tar.md5“ at the end of the filename.

  10. If you are ready with all the settings click on Start to launch the root process for your Samsung Galaxy Alpha
  11. The root process should finish after a few minutes and your phone should reboot automatically into the recovery-mode (if your phone doesn’t reboot automatically you need to start over with this tutorial. In this situation we recommend to pull out the battery at step 4)
  12. As soon as your device reboots back into Android you can disconnect the phone from your pc
  13. Thats it, your Samsung Galaxy Alpha Root is done 🙂

After rooting your Samsung Galaxy Alpha

If you encounter Problems like reboots after the root do the following.

Launch SuperSU on your Smartphone. The App should now inform you that KNOW was detected and wants you to deactivate it. You will need to accept this and then wait until KNOX is deactivated (this can take up to 5 minutes). After this you should head over to your „system/app“ and „system/priv-app/“ folders and delete all apps that have „KNOX“ in the name. This should fix problems like unexpected reboots.
